The sinking of the Moskva and several concurrent strikes on Russian border towns by Ukraine seem like a coordinated escalation aiming to provoke a like response from Russia.
Whether it is its intention or not, Ukraine's actions will probably result in the Russian public wanting an increased use of force in Ukraine, which had been held back due to Russian President Vladimir Putin’s assertions that the Russians and Ukrainians are a common people.
Deliberately goading Russian escalation
The United States will help Ukraine to target disputed Crimea, considered core Russian territory by Moscow. The US may not recognise Russian sovereignty over Crimea, but the Russian government does. Therefore, should such strikes occur, they will be considered no different than strikes on the centre of Moscow ordered from Washington.
Even as it engages in the above risky policy, the United States is giving CBRN (chemical, biological, radiological, nuclear) suits to Ukraine, as if to prepare them to fight in radioactive wastelands. It seems as though the Ukrainians, led by the US, are expected to destroy their own country to save it, just to assert their nationalistic zeal.
The United States speculates openly about when Russia will get desperate enough to use a tactical nuclear weapon. Based on the tone, it seems as if they are certain it will happen, and are willing to maintain all policies with no interest in preventing it.
Scorched earth?
All of this shows clearly that the United States doesn’t stand with the people of Ukraine. It is primarily looking at frustrating Russia rather than preventing harm to Ukraine. Someone who stands with the people of Ukraine would not want it to become a nuclear wasteland, nor would they even believe it is wise for it to fight Russia in the first place.
But what does the US gain from nuclear detonations in Kiev, or elsewhere in Ukraine? We can only suppose the US might want this outcome just to incriminate Moscow and to convince the world of Western moral superiority, as the US had previously been the only country to ever use nuclear weapons in a war (a fact rival countries like to remind it of). It may also secretly view Ukraine as Russian territory, itself, and be wanting the lands burned and uninhabitable to punish the Russians.
If the US believes its power is in terminal decline, it might believe that incriminating a rival regime in the most barbaric act of the Twenty-First Century would give the United States vast moral authority against such rival regimes. Ultimately, it could mean excluding such regimes from the United Nations entirely, giving total control of the international system to Washington.
Russian and Chinese restraint
Russia seems not likely to use nuclear weapons yet, as there is no sign it is even interested in a troop surge or a strategic bombing campaign yet, although Russian generals suggested they could target Ukraine’s decision-making centres.
The US is encouraging conflicts at the peripheries of its rivals, while confusing gullible audiences at it home that it is somehow deterring aggressors. The same is certainly true of Taiwan, where almost the exact same policy is being pursued, despite it spectacularly failing to prevent conflict in Ukraine. This shows they are not sincere about preventing conflicts, in fact seeking conflicts and building traps at the doorsteps of their rivals in the hope to weaken them.
